Serial No. 755,303.

To (ZZZ whom it may concern:

Be it known that we, Fonusr T. BARTON and Oscar Hanson, citizens of the United States, residing at Seattle, in the county of King and State of W ashington, have invented certain new and useful Improvements in Show-Case Doors, of which the following is a specification.

This invention relates to improvements in show-cases or cabinets for exhibiting merchandise and has for its object the provision of a door of novel construction and operation whereby it may be opened and closed within a narrow space and when open is wholly contained within the case.

The invention consists in the novel construction of a show-case or cabinet and the combination and adaptation therewith of devices whereby said door may be slidably operated to open and close the same, as fully explained in the following specification, illustrated in the accompanying drawings, and finally set forth in the appended claims. In said drawings, Figure 1 is a view partly in front elevation and partly in vertical section of a case embodying our invention. Fig. 2 is a cross sectional view through line 22 of Fig. 1. Fig. 3 is a fragmentary horizontal sectional View, looking upward, showing the underside of the casetop. Fig. 1 is a detached view in front elevation of a door. Figs. 5 and 6 are detached views in side elevation and top plan, respectively, of details of the invention.

Referring to said drawings, the reference numeral 1 designates the base of a showcase, 2 the floor, 3 the end walls and 4, the rear wall. Said walls are desirably provided with glazed panels and support the top 5 arranged in a plane parallel with said floor. As illustrated, a pair of doors 6 and 7 are provided inclosing the front of the case and each is formed with top and bottom rails S and 9 and front and rear stiles 10 and 11, respectively. Vertically alined protruding pins 12 and 13 are positioned at the opposite extremities of the rear stile 11 of each door and a similar pin 1% is provided in the top rail 8 in approximately the vertical axis of the door. Each door is further provided with a channel 15 extending along its lower edge from the forward end of the lo *er rail 9 to a point somewhat past said vertical axis of the door where said channel terminates in a square shoulder or stop 15 At each end of said case a groove 16 substantially rectangular in cross-section is formed in the floor 2 extending from the proximity of the rear wall t parallel to and adjacent the proximate side wall 3 to the forward portion of the case where it is continued in a rectangular direction, as at 17, parallel to the front edge of said floor. A similar though inverted groove 18 having a corresponding rectangular portion 19 is formed in the under side of said top 5, the corresponding portions being in direct vertical alinement.

Referring to Figs. 5 and 6 which show a roller support for the door, the numerals 20 and 21 designate a pair of practically similar frames pivotally connected together at 22. Pairs of rollers 23 and 2a are respectively rotatably mounted in lugs 25 extending in opposite directions from said frames.

\Vhen assembled, the doors 6 and 7 are adapted to close the front opening of the show-case; the pins 12 and la being received within the groove 1819 and the pin 13 in the groove 16. Of the roller support, the frame 21 is received within the groove-portion 17 and the frame 20 within the channel 15 of the door, the latter being supported upon the rollers 23. When thus assembled, and the door is in closed condition, as illustrated at the right hand side of Fig. 1, the channel 15 of the door and the groove-portion 17 overlap for about the space required to accommodate said roller support, the pivot 22 of which is in substantially the vertical axis of the door and in alinement with the pin 14. When thus positioned within said groove and channel with the door in closed condition, the said frames have their longitudinal axes in parallel relation and both are parallel with the horizontal axis of the door. The door is opened by pulling outwardly upon the stile 10 which causes the door to swing upon its vertical axis; that is to say, upon the pivots 14c and 22, while the pins 12 and 13 are receded along the grooves 18 and 16, respectively, and causing said pin and roller support to travel longitudinally of the groove'portions 17 and 19 toward the adjacent side wall of the case. In such transition the door will assume the position indicated by dotted lines 6 in Fig. 2, and the upper frame 20 of the roller support contained within the channel 15 of the spirit the door will swing therewith, as indicated at 20 in said view, while the roller support as a whole and the pin lat are slid in the respective groove portions 17 and 19 until they reach the intersections of said groove parts with the grooves 16 and 18, whcreat the door will he in the position shown in dotted lii es i at the left hand side of Fig. 52. in such position, the door and the upper tranie 20 within the channel 15 are in alineinent wit the groove 16 ano with a push upon the forward rail. 10 of the door it is receded within the ease to the position indicated by full lines at the lett hand side of Fig. 2. The roller support relnains fixed at the said intersection of the lower groove parts and the door is supported during such rearward movements with the minimum of friction or resistance by the rollers 2-3. The pins 12, 13 and i l assist in the guidance of the door rearwardly in the grooves. To close the door, the movements described are reversed; that is to say, the door is drawn outwardly upon the roller 4 .23 o l? the support in directions parallel to the adjacent side wall 3 until the pin i l is positioned at said intersection of the groove portions, then the door is swung laterally with the roller support upon the rollers Z'Z-l: until the door is in rectangular relation to said side wall The invention simple in construction and operation and extremely eilicient in use. There are no fixtures exposed to view, while the parts are tow and not liable to out of order. ll hile being overated the door does not project out into the adjacent aisle more. than. half of its length and when fully closed it is wholly contained within the where it is coni pactlv retained near the side walls and atlerds unobstructed access to the interior of the cabinet.

Various modifications of our invention may obviously he made and we expressly reserve all such changes in detail within the scope of the :lainis as may be made within of the invention and without sacrificing its advantages; for instance, the roller support may he made without the rollers, being formed of a pair of blocks pivotally connected together and each member thereof filling and slidably received in the door channel 15 and the groove portion 1?, respectively.
